How to reset completly a theme?

Hi, I'm trying to use the Bueno theme but would like to change a few options. In the process I have broken something and want to go back to how it originally looked, as it's shown in the photographic preview of the theme, but can't. I have erased all my code and saved, but for some reason it doesn't go back to it's original state. Some things do look how they should, others don't. For instance, the dotted background image doesn't come back nor the background image of the date of the posts, the color of the links is also wrong. I've tried changing themes, but no luck. Even the preview button shows it with the theme incorrectly applied. Is there something I'm missing? I have looked for in the support pages and the forum and can't find the answer.

I'm using both Firefox and Safari for Mac and have the CSS upgrade for my blog.

If you inserted a background image you must remove it from here > Background
If you chose to use a colored background you must remove it also from here >
Background
Then go to the theme Options page and make your color scheme selection there and click "Save Changes"
If you uploaded a header image then delete it from your Mdeia Library so it cannot be displayed.

In other words, remove everything you injected into the theme must be removed and then it will revert.

I apologize for the weird text above I'm having a poor vision day. Please post the URL for the blog in question starting with http:// when you post for support. It makes things so much easier for Volunteers when we can see exactly what you are referring to, and when we can see it then we can provide better advice.

Here's how to link your wordpress.com blog to your username. Go into your dashboard -> Users -> Personal Settings -> then scroll down to 'Account Details'. In the spot where it says 'website' enter the full URL for your wordpress.com blog starting with http:// and save the changes.

I have changed my theme back to Benevolence because I can't leave it as it was.

The issue you mention in the other post doesn't really relate to me and I believe the answer you give is the best, at least it's what I also did at first.

About my problem, I did actually erase everything before posting here but there was no luck. Since I don't know what else to do, my imagination has gone wild and here is my current theory:

We all have copies of the original versions of the themes and somehow I managed to break my copy, and eventhough I switch themes, when I revert to Bueno, I still have the same issues. I say that because I know other people using Bueno are not having this problem, but as I said, it's a wild guess.

Other issues I'm having: some fonts are changed, alignment of everything is in the middle

When new themes are introduced there are always wonky bits. We report the weirdness to Staff and the Theme Team sill sort them. Please file a support ticket and don't despair. They will "fix" whatever went wrong. Here's the link > http://en.support.wordpress.com/contact/

@jazzmic
You're welcome but even though you have switched themes to Vostok now, it would be helpful if you filed a support ticket for the Theme Team. That way they will know the problem exists and can fix it before the next blogger has a similar experience.

Answer in English: You are posting to the wrong forum for the software you use. This forum is only for wordpress.COM bloggers. We cannot help you here. You must post to this forum to get help with that bloghttp://wordpress.ORG/support/

Hm.... no, still no luck. Support told me it was something to do with a bug and it should be ok now, but it isn't. I think that somehow the url to the images got erased, or at least I read something like that could happen if copying the complete CSS to the style editor and I think I did... Still, there should be an option to reverse that.
